Most electrical problems are a symptom of something you can't see. OSB finds the actual fault in Tyngsboro homes and businesses — the loose neutral, the failed backstab, the shared circuit — instead of guessing at parts.
“The dispatcher actually understood what I was describing on the phone and told me which breaker to shut off before they arrived.”
“They rewired our restaurant kitchen overnight so we never closed a single service. That mattered more than the price, honestly.”
“Garage had one outlet and a light on the house circuit. Now it has a sub-panel and I can actually use my tools.”
That's the job. We isolate circuits, test under load and trace the run until the actual fault shows itself — no guessing, no parts cannon.
Three causes: overload, short circuit, or ground fault. Each has a different fix, and testing tells us which one it is within the first visit.
Most Tyngsboro repair calls are handled same-day, and emergencies are dispatched 24/7 at (833) 652-8933.
There's a flat diagnostic fee quoted on the phone, and it's credited toward the repair when you go ahead.
Yes. We produce written inspection findings for Tyngsboro home sales, insurers and landlords.
